A portable device for extemporaneous analysis of a body fluid in an intracorporeal cavity includes a tube adapted for introduction into the cavity and a rod slidably mounted in the tube. The rod has a gripping end which emerges from one end of the tube, and a second end that has elements for sampling of body fluid. The rod is capable of assuming two relative positions with respect to the tube, one retracted and the other deployed. The second end of the rod has two branches which can be spaced apart angularly, and the free end of each of the branches has elements for sampling of the body fluid. The branches are arranged in relation with the tube in such a way that, in the retracted position, the sampling elements of the two branches are drawn together and remain at a distal end of the tube, and in the deployed position, the branches are spaced apart outside the distal end of the tube.
